A comparison of psychedelic and imaginative experience is presented. The two terms "psychedelic" and "imaginative," are taken to refer to a fundamentally identical power of apprehension, or mode of being. This power, or mode, is discussed as it is described in psychedelic reports and manifested in works of literature. Certain visionary, philosophical, and metaphysical elements recur in a high percentage of psychedelic reports and appear to constitute a fairly consistent dimension of the experience. The main focus in this document is on "the extroverted experience." The point is made that if it can be shown that a predominant kind of drug-educed experience is closely comparable in important respects with a major kind of our literature, it must conduce to a greater understanding of and trust in, the parapsychic effects of those extraordinary substances. The intent is to provide a running commentary of literary passages bearing upon the psychedelic issue. (Author/CK)
